XCOMM
XCOMM Do the equivalent of the 'makedepend' program, but do it right.
XCOMM
XCOMM Usage:
XCOMM
XCOMM makedepend [cpp-flags] [-w width] [-s magic-string] [-f makefile]
XCOMM [-o object-suffix]
XCOMM
XCOMM Notes:
XCOMM
XCOMM The C compiler used can be overridden with the environment
XCOMM variable "CC".
XCOMM
XCOMM The "-v" switch of the "makedepend" program is not supported.
XCOMM
XCOMM
XCOMM This script should
XCOMM work on both USG and BSD systems. However, when System V.4 comes out,
XCOMM USG users will probably have to change "silent" to "-s" instead of
XCOMM "-" (at least, that is what the documentation implies).
